Oct 26, 2017  Step Eight: Log Into macOS High Sierra. Eventually the virtual machine will reboot again, this time into macOS High Sierra. If that doesn’t happen, try ejecting the ISO from the Virtual Machine. When High Sierra does boot, you’ll need to go through choosing your country, setting up a user, and the rest of the initial setup process.

High Sierra Format (HSF) is the early logical file system used for CD-ROMs in 1985 and 1986. The later ECMA-119 and ISO 9660 standards are based on revised HSF.

The Apple File System (APFS) is the file system used with Mac devices running macOS 10.13 High Sierra and later, while the older Mac OS Extended file system is available for older versions of macOS. You can still use either file system for your hard drives and attached. I have been running High Sierra on an internal SSD (on a PCI card) in my 2012 Mac Pro for several weeks now, but today I received a notification from the App Store that I should update my software. When I chose to update, the updater ran and the Mac restarted and then just blank screens! Sep 25, 2017 Wait for macOS High Sierra to install and your Mac to restart. When your Mac has restarted, you’ll need to follow the process of setting it up as if it was a brand new Mac. So, you’ll need to connect to your wifi router and type in the password. When promoted, select “Mac OS Extended (Journaled) as the format type, with GUID Partition Map as the scheme. Note that if your Mac can be converted to the new APFS file system, it will happen during the macOS High Sierra installation. At this point, it’s perfectly fine to use the “old” format defaults.

Overview[edit]

Compact Discs were originally developed for recording musical data, but soon were used for storing additional digital data types because they were equally effective for archival mass data storage.

At first, every CD-ROM maker created their own format as there were no high-level standards, only the Yellow Book CD-ROM standard for the lowest level. There was a need for a standard for organizing data on compact disks into logical units such as files.

In order to develop a CD-ROM file system standard (Z39.60 - Volume and File Structure of CDROM for Information Interchange), the National Information Standards Organization (NISO) set up Standards Committee SC EE (Compact Disc Data Format) in July 1985.[1]

In September/[2] October 1985 several companies invited experts to participate in the development of a working paper for such a standard.

In November 1985, representatives of computer hardware manufacturers gathered at the High Sierra Hotel and Casino (currently called the Hard Rock Hotel and Casino) near Lake Tahoe, California.[3] This group became known as the High Sierra Group (HSG).

Present at the meeting were representatives from Apple Computer, AT&T,[citation needed]Digital Equipment Corporation (DEC), Hitachi, LaserData, Microware,[citation needed]Microsoft, 3M, Philips, Reference Technology Inc., Sony Corporation, TMS Inc., VideoTools (later Meridian[4]), Xebec, and Yelick.[citation needed]

The meeting report evolved from the Yellow Book CD-ROM standard for data CDs, which was so open ended it was leading to diversification and creation of many incompatible data storage methods. The High Sierra Group Proposal (HSGP) was released in May 1986.

A draft version was submitted to the European Computer Manufacturers Association (ECMA). With changes this led to the issue of the initial edition of the ECMA-119 standard in December 1986.[5] The ECMA submitted their standard to the International Standards Organization (ISO) for fast tracking, where it was further refined into ISO 9660. For compatibility the second edition of ECMA-119 was revised to be equivalent to ISO 9660 in December 1987.[6][7][8]ISO 9660:1988 was published in 1988. ECMA-119 and ISO 9660 were needed because the HSF was geared primarily towards the needs of the US market. The international extensions are the bulk of the differences between the formats.

In order not to create incompatibilities, NISO suspended further work on Z39.60, which had been adopted by NISO members on 28 May 1987. It was withdrawn before final approval, in favour of ISO 9660.[1]
